## NAME
       deb-md5sums - package MD5 file digests

## SYNOPSIS
       DEBIAN/md5sums

## DESCRIPTION
       A package declares the MD5 digests for the package file contents by including an md5sums file
       in its control archive (i.e. DEBIAN/md5sums during package creation). This file is used for
       integrity verification and deduplication purposes, and not for any kind of security purpose.

       This file contains a list of MD5 digests (as 32 case-insensitive hexadecimal characters)
       followed by two spaces (U+0020 SPACE) and the absolute pathname of a plain file, one per
       line.

       Trailing slashes (U+002F /) in the pathname will be trimmed.  Neither trailing whitespace nor
       empty or whitespace-only lines are accepted.

       If the control file does not exist in the binary package, [dpkg(1)](https://www.chedong.com/phpMan.php/man/dpkg/1/markdown) will generate the matching
       information at unpack time (since dpkg 1.16.3).
